' MECHANISM FOR ELEVATING TORPEDOES ZI NTO MOUTHS OF WELLS.

5 'Ohio, have invented a} new and usefulQIm- A provement in Mechanism for Elevating Tor pgdoes to the Mouths offWells, of which the llowing is a ful1,-cle'ar and etaotdescrip- (i to the accom any:

m ing '-.drawmgs, which form a spart I this specification.

v In task torpedoes in firingwells', for 111- ,stance oil wells it is necessary'to'elevate the torpedo tromthe ground to'the mouth of the ower it properly into the well; The object'ef my invention is'to provide-a simpleconstruotion' which will 'enable' the torpedo to be readilyiattached to the elevat- 20 ing device, safely elevated, and alined in the p j cting tube so that when the bail is at-i tached to the lowering ro e or cable to allow 1 itto descend into the we 15 it will properly pass-downward. In general I accomplish this; result by: provi din v the can containingthe wni-troglyceninpr Q or ex losive with a ring? secured to its uppei' sur ace. This ringis pre erab y: fo m d. of s o I is P YlfaBlhZw'l JjWflflgim' h n a lu ce 9 80 which. i iormsd'ieii'gm v T e fi s i9 mefii stb spanrw r he li cable elevator; comprises twojjaws pivota lly eon-E- ne cted and projecting gn s and an. inter-l I mediate flat portion havmg-acurved vertical 85 inner surface, the projecting arms bein pro- 111g ange which,.-when the jaws are rought 40 together around the'ii'iig' connectedto the 4-6 .cirlelthe can rm "they-are locked; and the bails are connects to 'the elevating apparatus, the can is then elegated and swung over the mouth of theprojcting' well. pipe and lowered untilthe-fiatr'surface of the jaws.

of this can he d'oiie' without any danger, as

the exp1osive-canortorpedo is firmly held, by tlie seating or resting of the flat surface of lowere "into thewell." ..I .w'il now describe the embodiment of my invention .illustratedin the accompanying drawing, in which.- r

Secured to the to' of-thisca'n by.riv;ets or ;bolts is.the ring. which may 'be a casting, and of east ii'on. --T he 11' per portion of this T'JIin titles the flan ge e, 51 the'face of which is: ormed'the gr' Tve jL I 3 fl 9, g, are twoj "ws jeachha'vingr the-projecting portion h'h'avifig an orifice z t hrou gh *d e'r surface by nu 70 passes; thus forming a hinge'for the jaws. The centralor main pfo IiQnof each of taesefiaws has a vertical cufved surface provided with an inwardly projeiti ig flange m.

the roove-o in which. the flange m enters.

Eac of these plates'has aprojecting flange p adapted to enterthe roove 'f in the flangepf ring'd. These p ates are secured to their respectivefjaw'members by means of set screws g. The. flat horizontal surface .of thetplates n of the jaws g, g, are of such width as to rest securely in the top of pipe b. 'Each of these jaws g,'g, isalso provided with a projecting arm '1". To one of these arms is pivotally secured the strap 8 and with the operating 'handle M.

Then the torpedo or explosive can may be ing device at rlghta-n les 10,111" 3 and shown in connection wit the top 0 the tora r .I -15 a Is the well, 6 the pipe 'projeoting-there-- ractioe this pipe projects about I the jaws on the to""'of-the pipe.

nected together, as described, the are encircled around the rin d so that t e flanges p enter the groove he arms 1- r are then moved toward eac other and the. strap 8 brought over the other jaw g and the arms 1" r moved until the flanges p are securely fitted in the cove f when the cam is operated to 'loc the two jaws fixed in that position. -To the main body of each of the aws is pivotally connected a bail o by which the jaws are connected to the elevator. The elevator then lifts the can. The can is swun over and lowered until it enters the and the flat surface of the jaws rest upon the top of said pipe securel holding thetor edo until the lowering cab e or ro e is attac ed to the bail 20 connected with t e top of the ring. Then the lock is released and the jaws swing free, or the pivot bolt maybe removed and the jaws separated. With his arrangement I provide security, in lifting the torpedo, brin 'ng it to proper position, adjusting it an securing to it the lowering cable. v

As may be 'seen, the jaws ma be moved to adapt, themselves to coact with vargin'g seized torpedoes and the plate portion 0 the jaws are removable so that plates of the pro or size forthe torpedo may be inserted on secured. I

Having now fully described my invention, what Ic aim and desire to protect by Letters Patent is: i r
